Letters Patent No. 71,898, dated December 10, 1867.

IMPROVEMENT IN BOOTS AND SHOES.

TO ALL WHOM IT MAY CONGERN:

j Be it known that I, CHARLES MOLE, of Pembroke Terrace, Regents Park, London, boot and shoe manufacturer, haveeinvented Improvements in the Manufacture of Boots and Shoes;`and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying sheet of drawing,

making apart of this specitication, and to the figures and-letters of reference marked'thereon, similar letters of reference denoting similar parts where such parts .appear or may be seen at each of the gures respectively.

The nature of mfy invention consists in so making the heel of a boot or shoe that the wearer may, with great facility, turn tholower part thereof, and 'thus bring an uneven portion of the bottom or tread into the position previously occupied by a. part of the tread, which, from being subjected to the greatestwear, shall have become uneven with the remainder of the bottom of the heel. i

`I am aware that movable and revolving heels have, in many instances, been applied to boots and shoes for the purpose above set forth, but in every case the Vmethods adopted here labored under the ,disadvantages of being too expensive, too complicated, or otherwise inelieetive. r

I construct my boot-heel in two parts, and screw or otherwise fasten a disk or plate of brass, bronze, or other suitable metal or material, on to the under side of the toppart, and a plate of the same material on to the upper surface of the lower part, so that, when the two parts of the heel areplaced together, these two plates are `brought into juxtaposition.' In the centre of one of the metal plates, the top or bottom one, indilierently,

,I cut a square hole, passingV either through o r only partially through the thickness of the plate, and on` the other plate, which is to be brought into juxtaposition with it, I form a projection, the shape of which will bev the exact counterpart of the hole in the first-mentioned plate. The-*two parts of the heel will be secured together by a pin passing through a. hole in the centre of the lower part of the heel, and which may eitherform f part of the top-plate, in which casi'e its shoulder may form the `square or other projection which is to take into j 'Y the hole or slot made in the under plate, and its lower end will be screw-threaded, toreceive a. dat nut of brass or other suitable metalor material, which, when the two plates are brought close together, will be countersunlc in the bottom or tread ofthe heel. But this piu may also pass up from the tread of the heel; in which easev its head will take the place of the nut above mentioned, and the pin will be screw-threaded at that part which passes through the hole in the-centreof theV top and bottom-plate, which hole .will also be screw-threaded, and` thus the two parts of the heel will be drawn tightly together. AIt will beevident that if `the pin or4 screw forms part ofthe top-plate the lower plate only will have a hole through its centre. This method of fastening is much moreV certain end durable than any spring-fastening,;and also less expensive. y i

' Figures 1, 2, 3, and 4, of the annexed sheet of drawing, illustrate the construction of a manis boot-heel made according to my invention, iig. 1 being a vertical section through the centre of boot-heel, and figs. 2, 3, and 4 detached parts of same. a, top-plate, (shown detached at iig. 2;) b, bottom-plate, (shwn detachedy at iig. 3;) c, .pin or screw passing from topfplate through lower plate and bottom part of heel,.where it is secured by the nut ,'whieh has two slots, c, (see iig. 4,) in order that it may be unscrewed with a key provided for that i v purpose; f (figs. 1 and 2) is the projecting square piece which takes into the sunken square g of the plate Z, ('see figs. 1 and 3;) h, lower part of heel; z', tread orl bottom of heel; j, screws fastening plateto heel, and Ic,

hole for passage of pin -cA l The action is as follows: Whenl it is desired tojturn thev lheel and bring another part ofthe tread into the place most subject to wear-,thc nut d is nnserowed from' the pin c, either wholly or enough to permit the lower part It of the heel to be moved sufficiently from the top part or plate a that the projecting square f may come out of the sunken square g, leaving the part h'free to be turned round,`rigl1t or left, and when-it has received one quarter turn, the projection f can drop again into the sunken square g, and the wholebe again secured in position by screwing up the nut d, or, the part h may receive another quarterturn, and be then secured.

Figures 5,6, 7, and 8 illustrate a. maus boot-heel made according to my invention, the fasteningscrew or pin c passing up from beneath, and not forming part of the top-plate a. Fig. 5, vertical section through centre of'bootheel. Fig. 6, top plan view of bottom part of heel b,"botto'm plate or disk; g, sunkensquare; V h, boot heel. Fig. 7, bottom plan view of top part of heel; a, top plate; j, projecting square; Z, top part of heel. It

will be observed that in this arrangement the plates or disks a and b are countersunk in their respective parts of the heel, and that their rims do no t appear on the exterior, as at iig. 1. Fig. 8, pin c detached; m, slot foro screwin u Here the screw casses from the tread zu throufrh the lower. art lt of the heel and thi-ouch g P P P e P o the plates b und a, the central holes in which are screw-threaded. By unserewing the pin c two or three turns i the projectionfmayhe drarvn out cfg, and the lower purt'of the heel become free to be turned as may be required. 3 I

Figure 9 illustrates the application of the lust-described arrangementr to the heel of a ladys boot. The plates a and b may he 'placed near thetop ofthe heel, in the centre or elsewherefats may be desired. l

My experience leads me' to believe that less than a. quarter turn ofthe lower part of the heel will-rarely be required, and I would therefore usually use a, square projection and hole or slot; but my projecting piece may l be made sexagonal, octagonal, or present any desired number of sides, s o that the slot-hole or countersunk part which is to receive it he of precisely'the samelshupe. l v

And having now described the nature of my said invention, and the means hy which I carry-it into prae tical eil'ect, I would have' it understood that I do not c onine myself to the exact details herein given, nor to any precise dimensions of the several parts, s such may be varied and modiied'without departure from my invention; but

What I claim as of my invention, and desire to secure by Letters Patent, is'- The manufacture of a. movable bootheel in two parts, to be adjusted in diiierent positions by means of a single central projection taking into a single slot-hole or cou'ntersunk part, and secured in position by means of a. central screw or pin, Whether such projection and hole or countersunk part be square or many-sided, and no matter what the shape of these sides, so 'that the shape of the projection and that ot` the hole which is to receive it be identical, the whole substantially as hereinbefore described and illustrated `on the annexed sheet' of drawing.

CHARLES MOLE.
